maturing in less than or more than one year, plus all bonds, notes, debentures
or similar debt instruments plus all capitalized lease obligations plus the
present value of all basic rental obligations under any synthetic lease.

         "Transactions" shall have the meaning assigned to such term in Section
3.2.

         Terms Generally. The definitions in Section 1.1. shall apply equally to
both the singular and plural forms of the terms defined. Whenever the context
may require, any pronoun shall include the corresponding masculine, feminine and
neuter forms. The words "include", "includes" and "including" shall be deemed to
be followed by the phrase "without limitation." All references herein to
Articles, Sections, Exhibits and Schedules shall be deemed references to
Articles and Sections of, and Exhibits and Schedules to, this Agreement unless
the context shall otherwise require. Except as otherwise expressly provided
herein, all terms of an accounting or financial nature shall be construed in
accordance with GAAP, as in effect from time to time; provided, however, that,
for purposes of determining compliance with any covenant set forth in Article
VI, such terms shall be construed in accordance with GAAP as in effect on the
date of this Agreement applied on a basis consistent with the application used
in the Borrower's audited financial statements referred to in Section 3.5.

           THE CREDIT

         Commitment. Subject to the terms and conditions and relying upon the
representations and warranties herein set forth, Lender agrees to make Revolving
Loans to the Borrower, at any time and from time to time and until the earlier
of the Revolving Credit Maturity Date and the termination of the Revolving Loan
Commitment in accordance with the terms hereof, in an amount not to exceed the
Revolving Loan Commitment. Within the limits set forth in the preceding
sentence, the Borrower may borrow, pay or prepay and reborrow Revolving Loans on
or after the Closing Date and prior to the Revolving Credit Maturity Date,
subject to the terms, conditions and limitations set forth herein. Each advance
under the Revolving Loans (each such advance is referred to herein as a "Loan")
shall constitute either a LIBOR Rate Loan or a Base Rate Loan, subject to the
following conditions:

                           (A) Each Loan that is made or continued as a LIBOR
Rate Loan shall be made or continued on such

Business Day, in such amount (equal to $100,000.00 or an integral multiple
thereto), and with such an Interest Period as the Borrower shall request by
written notice given to the Lender no later than 11:00 a.m. (Denver, Colorado
time) on the third Business Day prior to the date of disbursement or
continuation of the requested LIBOR Rate Loan. Each written notice of any LIBOR
Rate Loan shall be irrevocable and binding on the Borrower and the Borrower
shall indemnify the Lender against any loss or expense incurred by the Lender as
a result of any failure by the Borrower to consummate such LIBOR Rate Loan,
including, without limitation, any loss (including loss of anticipated profits)
or expense incurred by reason of liquidation or reemployment of deposits or
other funds acquired by the Lender to fund the LIBOR Rate Loan. A certificate as
to the amount of such loss or expense submitted by the Lender to the Borrower
shall be conclusive and binding for all purposes, absent manifest error. In the
event that the Borrower fails to provide the Lender with the required written
notice, the Borrower shall be deemed to have given a written notice that such
LIBOR Rate Loan shall be converted to a Base Rate Loan on the last day of the
applicable Interest Period. In no event shall the Borrower be permitted to
select a LIBOR Rate Loan having an Interest Period ending after the Maturity
Date;

                  (B) Each Loan that is made as a Base Rate Loan shall be made
on such Business Day and in such amount (equal to $50,000.00 or any integral
multiple thereof) as the Borrower shall request by written notice given to the
Lender no later than 11:00 a.m. (Denver, Colorado time) on the date of
disbursement of the requested Base Rate Loan.

                                       11
<PAGE>

         Note. The Revolving Loans shall be evidenced by the Revolving Credit
Note dated the date hereof. The Revolving Credit Note shall be a master note,
and the principal amount of all Revolving Loans outstanding shall be evidenced
by the Revolving Credit Note or any ledger or other record of the Lender, which
shall be presumptive evidence of the principal owing and unpaid on the Revolving
Credit Note.

         Notice of Borrowings. The Borrower shall give the Lender written notice
not later than 2:00 p.m., Denver, Colorado, time, on the same Business Day that
a proposed borrowing under the Revolving Loan Commitment (a "Borrowing"). Such
notice shall be irrevocable, shall in each case refer to this Agreement and
shall be in the form attached hereto as Exhibit A. Each notice of Borrowing
shall be deemed a representation by Borrower that all conditions precedent to
such Borrowing have been satisfied.

         Note; Repayment of Loans. The Revolving Credit Note shall bear interest
from the date of the first Borrowing on the outstanding principal balance
thereof as set forth in Section 2.6. The Lender shall, and is hereby authorized
by the Borrower to, endorse on a schedule attached to the Revolving Credit Note
(or on a continuation of such schedule attached to such Note and made a part
thereof), or otherwise to record in Lender's internal records, an appropriate
notation evidencing the date and amount of each Revolving Loan, each payment and
prepayment of principal of the Revolving Loans, each payment of interest on the
Revolving Loans and the other information provided for on such schedule;
provided, however, that the failure of the Lender to make such a notation or any
error therein shall not affect the obligation of the Borrower to repay the
Revolving Loans made by Lender in accordance with the terms of this Agreement
and the Revolving Credit Note.

         Fees.

         The Borrower agrees to pay an origination fee (the "Origination Fee")
in an amount equal to $2,250, which shall be paid on the Closing Date.

         A commitment fee (the "Commitment Fee") of .25% per annum on the
average daily unused amount of the Revolving Loan Commitment during the
preceding quarter shall be payable, in arrears, on the last day of each quarter,
commencing September 30, 2003, and continuing on the last day of each quarter
thereafter until the Revolving Credit Maturity Date. The Commitment Fee shall be
computed on the basis of the actual number of days elapsed in a year of 360
days. The Commitment Fee due September 30, 2003, shall be prorated based on the
number of days from the Closing Date through September 30, 2003, divided by the
number of days in the quarter ending September 30, 2003.

         All Fees shall be paid on the dates due, in immediately available
funds. Once paid, none of the Fees shall be refundable (absent a calculation
error) under any circumstances.

         Interest on Loans. The Borrower shall pay interest on the unpaid
principal amount of each Loan from the date such Loan is made until such
principal amount shall be paid in full as follows:

                           (a) (i) With respect to any LIBOR Rate Loan, at a
rate per annum equal to the sum of the LIBOR

Rate effective as of the date such LIBOR Rate Loan was made and the LIBOR Rate
Margin specified in subpart (b)(i) below.

                                    (ii) With respect to any Base Rate Loan, at
a rate per annum equal to the sum of the Base Rate

and the Base Rate Margin specified in subpart (b)(i) below, which rate shall
change when and as the Base Rate changes in accordance with this Agreement.

                                       12
<PAGE>

                           (b)(i)


                             LIBOR Rate Margin            Base Rate Margin
                          -------------------------- ------------------------
      Revolving Loan           200 Basis Points           50 Basis Points



                  (ii) The Borrower shall pay to the Lender accrued interest on
the unpaid principal balance of each Base Rate Loan on either (i) the date such
Loan is converted to a LIBOR Rate Loan, or (ii) the last day of each month,
whichever is earlier. The Borrower shall pay to the Lender accrued interest on
the unpaid principal balance of each LIBOR Rate Loan on (i) the date such Loan
is converted to a Base Rate Loan, or (ii) the last day of the applicable
Interest Period.

         Default Interest. If the Borrower shall default in the payment of the
principal of or interest on the Loans or any other amount due or becoming due
hereunder, by acceleration or otherwise, the Borrower shall on demand from time
to time pay interest, to the extent permitted by law, on such defaulted amount
up to (but not including) the date of actual payment (after as well as before
judgment) at a rate per annum (computed on the basis of the actual number of
days elapsed over a year of 360 days) equal to the Base Rate plus 4% (the
"Default Rate") From and after any Event of Default, the outstanding principal
balance of the Loans shall accrue interest at the Default Rate.

         Termination of Commitments.

         The Revolving Loan Commitment shall be automatically terminated at 5:00
p.m., Denver, Colorado time, on the Revolving Credit Maturity Date.

         The Borrower shall pay to the Lender, on the date of termination, the
Commitment Fee on the amount of the Revolving Loan Commitment so terminated
accrued through the date of such termination.

         Prepayment. The Borrower may prepay any Base Rate Loan in whole, or in
part, at any time or times. The Borrower may prepay any LIBOR Rate Loan, in
whole or in part, upon not less than three (3) Business Days' prior written
notice given to the Lender; provided, that, if payment of a LIBOR Rate Loan
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, the Borrower shall
indemnify Lender for any loss or cost incurred by it resulting therefrom,
including, without limitation, any loss or cost in liquidating or employing
deposits required to fund or maintain the LIBOR Rate Loan.

                  (b) The Borrower shall give prior written notice to Lender
before a proposed borrowing (a "Borrowing") pursuant to Section 2.3 hereof. Such
notice shall be irrevocable and shall in each case refer to this Agreement. Each
notice of Borrowing shall be deemed a representation by Borrower that all
conditions precedent to such Borrowing have been satisfied.

         Additional Costs.

         (a) If, due to either (i) any change in any law or regulation (or its
interpretation), or (ii) the compliance with any guideline or request from any
central lender or other governmental authority (whether or not having the force
of law), there shall be any increase in the cost to the Lender of making,
funding or maintaining LIBOR Rate Loans, then the Borrower shall from time to
time, upon demand by the Lender pay to the Lender additional amounts sufficient

                                       13
<PAGE>

to reimburse the Lender for any such additional costs. A certificate of the
Lender submitted to the Borrower as to the amount of such additional costs,
shall be conclusive and binding for all purposes, absent manifest error. Upon
notice from the Borrower to the Lender within five (5) Business Days after the
Lender notifies the Borrower of any such additional costs pursuant to this
Section 2.10(a), the Borrower may either prepay in full all LIBOR Rate Loans so
affected then outstanding, together with interest accrued thereon to the date of
such prepayment, or (ii) convert such LIBOR Rate Loans so affected then
outstanding into Base Rate Loans upon not less than four (4) Business Days'
notice to the Lender. If any such prepayment or conversion of any LIBOR Rate
Loan occurs on any day other than the last day of the applicable Interest Period
for such Loan, the Borrower also shall pay to the Lender such additional amounts
sufficient to indemnify the Lender against any loss, cost, or expense incurred
by the Lender as a result of such prepayment or conversion, including, without
limitation, any loss (including loss of anticipated profits), cost, or expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by the Lender to fund any such Loan, and a certificate as to the amount
of any such loss, cost, or expense submitted by the Lender to the Borrower shall
be conclusive and binding for all purposes, absent manifest error.

                           (b) If either (i) any change in any law or regulation
(or its interpretation), or (ii) the compliance

with any guideline or request from any central lender or other governmental
authority (whether or not having the force of law), affects or would affect the
amount of capital required or expected to be maintained by the Lender or any
corporation controlling the Lender and the Lender determines that the amount of
such capital is increased by or based upon the existence of the Loan (or
commitment to make the Loan) and other extensions of credit (or commitments to
extend credit) of similar type, then, upon demand by the Lender, the Borrower
shall pay to the Lender from time to time as specified by the Lender additional
amounts sufficient to compensate the Lender in the light of such circumstances,
to the extent that the Lender reasonably determines such increase in capital to
be allocable to the existence of the Lender's Loan (or commitment to make the
Loan). A certificate of the Lender submitted to the Borrower as to such amounts
shall be conclusive and binding for all purposes, absent manifest error. Upon
notice from the Borrower to the Lender within five (5) Business Days after the
Lender notifies the Borrower of any such additional costs pursuant to this
Section 2.10(b), the Borrower may either (A) prepay in full the Loan if so
affected, together with interest accrued thereon to the date of such prepayment,
or (B) convert the Loan if so affected into a Loan of any other type not so
affected upon not less than four (4) Business Days' notice to the Lender. If any
such prepayment or conversion of any LIBOR Rate Loan occurs on any day other
than the last day of the applicable Interest Period for such Loan, the Borrower
also shall pay to the Lender such additional amounts sufficient to indemnify the
Lender against any loss, cost, or expense incurred by the Lender as a result of
such prepayment or conversion, including, without limitation, any loss
(including loss of anticipated profits), cost, or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by the
Lender to fund any such Loan, and a certificate as to the amount of any such
loss, cost, or expense submitted by the Lender to the Borrower shall be
conclusive and binding for all purposes, absent manifest error..

         Payments.

         The Borrower shall make each payment (including principal of or
interest on any Borrowing or any Fees or other amounts) hereunder and under any
other Loan Document not later than 2:00 p.m., Denver, Colorado time, on the date
when due in dollars to the Lender at its offices at 1675 Broadway, Suite 500,
Denver, Colorado 80202, in immediately available funds.

         Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of
interest or Fees, if applicable.

         SECTION 2.12 Illegality. Notwithstanding any other provision of this
Agreement, if any change in any law or regulation (or its interpretation) shall
make it unlawful, or any central Lender or other governmental authority shall
assert that it is unlawful, for the Lender to perform its obligations hereunder
to make, continue, or convert LIBOR Rate Loans hereunder, then, (a) on notice
thereof by the Lender to the Borrower, the obligation of the Lender to make or

                                       14
<PAGE>

continue a LIBOR Rate Loan or to convert any Base Rate Loan into a LIBOR Rate
Loan shall terminate and the Lender shall thereafter be obligated to make only
Base Rate Loans whenever any written notice requests for any type LIBOR Rate
Loan is received, and (b) upon demand therefor by the Lender to the Borrower,
the Borrower shall either (i) forthwith prepay in full any LIBOR Rate Loan then
outstanding, together with interest accrued thereon, or request that the Lender,
upon four (4) Business Days' notice, convert any LIBOR Rate Loan then
outstanding into a Base Rate Loan. If any such prepayment or conversion of any
LIBOR Rate Loan occurs on any day other than the last day of the applicable
Interest Period for such Loan, the Borrower also shall pay to the Lender such
additional amounts sufficient to indemnify the Lender against any loss, cost, or
expense incurred by the Lender as a result of such prepayment or conversion,
including, without limitation, any loss (including loss of anticipated profits),
cost, or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by the Lender to fund any such Loan, and a
certificate as to the amount of any such loss, cost, or expense submitted by the
Lender to the Borrower shall be conclusive and binding, for all purposes, absent
manifest error.

indebtedness, obligation, or liability, absolute or contingent, matured or not
matured, with respect to the storage, treatment, cleanup, or disposal of any

         The obligations of Lender to make the Loan hereunder are subject to the
satisfaction of the following conditions:

         All Borrowings.  On the date of each Borrowing:

         The Lender shall have received a notice of such borrowing as required
by Section 2.3.

         The representations and warranties set forth in Article III hereof
shall be true and correct in all material respects on and as of the date of such
Borrowing with the same effect as though made on and as of such date, except to

Lender in connection with the preparation of this Agreement and the other Loan
Documents or in connection with any amendments, modifications or waivers of the
provisions hereof or thereof (whether or not the transactions hereby
contemplated shall be consummated) or incurred by the Lender in connection with
the enforcement or protection of its rights in connection with this Agreement
and the other Loan Documents to the extent Lender prevails or in connection with
the Loan made or the Note issued hereunder, including the fees and disbursements
of Brownstein Hyatt & Farber, P.C., counsel for the Lender, and, in connection
with any such amendment, modification or waiver or any such enforcement or
protection, the fees and disbursements of any other counsel for the Lender. The
Borrower further agrees that it shall indemnify the Lender from and hold them
harmless against any documentary taxes, assessments or charges made by any
Governmental Authority by reason of the execution and delivery of this Agreement
or any of the other Loan Documents.

                                       25

         The Borrower agrees to indemnify the Lender and its directors,
officers, employees and agents (each such person being called an "Indemnitee")
against, and to hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses, including reasonable counsel fees and
expenses, incurred by or asserted against any Indemnitee arising out of, in any
way connected with, or as a result of (i) the execution or delivery of this
Agreement or any other Loan Document or any agreement or instrument contemplated
thereby, the performance by the parties thereto of their respective obligations
thereunder or the consummation of the transactions contemplated thereby, (ii)
the use of the proceeds of the Loan or (iii) any claim, litigation,
investigation or proceeding by a third party relating to any of the foregoing,
whether or not any Indemnitee is a party thereto; provided that such indemnity
shall not, as to any Indemnitee, be available to the extent that such losses,
claims, damages, liabilities or related expenses are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or willful misconduct of any Indemnitee.

         The provisions of this Section 8.5 shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any of
the Loan, the invalidity or unenforceability of any term or provision of this
Agreement or any other Loan Document, or any investigation made by or on behalf
of the Lender. All amounts due under this Section 8.5 shall be payable on
written demand therefor.

         Right of Setoff. If an Event of Default shall have occurred and be
continuing Lender is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by Lender to or for the credit or the
account of the Borrower against any of and all the obligations of the Borrower
now or hereafter existing under this Agreement and other Loan Documents held by
Lender, irrespective of whether or not Lender shall have made any demand under
this Agreement or such other Loan Document and although such obligations may be
unmatured. The rights of Lender under this Section are in addition to other
rights and remedies (including other rights of setoff) which Lender may have.

         Applicable Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE
CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF COLORADO.

         Waivers; Amendment.

         No failure or delay of the Lender in exercising any power or right
hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any abandonment or discontinuance of
steps to enforce such a right or power, preclude any other or further exercise
thereof or the exercise of any other right or power. The rights and remedies of
Lender hereunder and under the other Loan Documents are cumulative and exclusive
of any rights or remedies which they would otherwise have. No waiver of any
provision of this Agreement or any other Loan Document or consent to any
departure by the Borrower therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) below, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. No notice or demand on the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances. Each holder of any of the Notes shall be bound by any amendment,
modification, waiver or consent authorized as provided herein, whether or not
such Note shall have been marked to indicate such amendment, modification,
waiver or consent.

         Neither this Agreement nor any provision hereof may be waived, amended
or modified except pursuant to an agreement or agreements in writing entered
into by the Borrower and the Lender.

         Interest Rate Limitation. Notwithstanding anything herein or in the
Notes to the contrary, if at any time the applicable interest rate, together
with all fees and charges which are treated as interest under applicable law
(collectively the "Charges"), as provided for herein or in any other document
executed in connection herewith, or otherwise contracted for, charged, received,
taken or reserved by Lender, shall exceed the maximum lawful rate (the "Maximum
Rate") which may be contracted for, charged, taken, received or reserved by
Lender in accordance with applicable law, the rate of interest payable under the
Note, together with all Charges payable to Lender, shall be limited to the
Maximum Rate.

         Entire Agreement. This Agreement and the other Loan Documents
constitute the entire contract between the parties relative to the subject
matter hereof. Any previous agreement among the parties with respect to the
subject matter hereof is superseded by this Agreement and the other Loan
Documents. Nothing in this Agreement or in the other Loan Documents, expressed
or implied, is intended to confer upon any party other than the parties hereto
any rights, remedies, obligations or liabilities under or by reason of this
Agreement or the other Loan Documents.

         Waiver of Jury Trial. Each party hereto hereby waives, to the fullest
extent permitted by applicable law, any right it may have to a trial by jury in
respect of any litigation directly or indirectly arising out of, under or in
connection with this Agreement or any of the other Loan Documents. Each party
hereto (a) certifies that no representative, agent or attorney of any other
party has represented, expressly or otherwise, that such other party would not,
in the event of litigation, seek to enforce the foregoing waiver and (b)
acknowledges that it and the other parties hereto have been induced to enter
into this Agreement and the other Loan Documents, as applicable, by, among other
things, the mutual waivers and certifications in this Section 8.11.

         Severability. In the event any one or more of the provisions contained
in this Agreement or in any other Loan Document should be held invalid, illegal
or unenforceable in any respect, the validity, legality and enforceability of
the remaining provisions contained herein and therein shall not in any way be
affected or impaired thereby. The parties shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

         Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute but one contract, and shall become effective as
provided in Section 8.3.

         Jurisdiction; Consent to Service of Process.

         The Borrower hereby irrevocably and unconditionally submits, for itself
and its property, to the nonexclusive jurisdiction of any Colorado State court
or Federal court of the United States of America sitting in Denver, Colorado,
and any appellate court from any thereof, in any action or proceeding arising
out of or relating to this Agreement or the other Loan Documents, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such Colorado State or,
to the extent permitted by law, in such Federal court. Each of the parties
hereto agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law. Nothing in this Agreement shall affect any
right that Lender may otherwise have to bring any action or proceeding relating
to this Agreement or the other Loan Documents against the Borrower or its
properties in the courts of any jurisdiction.

         The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this agreement or the other Loan Documents in any
Colorado State or Federal court. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense or an inconvenient
forum to the maintenance of such action or proceeding in any such court.

         Each party to this Agreement irrevocably consents to service of process
in the manner provided for notices in Section 8.1. Nothing in this Agreement
will affect the right of any party to this Agreement to serve process in any
other manner permitted by law.
